I installed led lights on 80 Noah. Since it is almost the same size as the normal T15 halogen bulb (a little slim), there is no problem in terms of size at all, it was loose when inserted in the socket.

They are very bright and pure white light, illuminating a wider light beam. Attached is a view of my rear view camera with stock lights and these led lights. All I'd like to say is that these are really going to allow you to safely be seen by pedestrians at a parking area; for example: just in case they don't know you intend to back up and if you don't notice them continue to pass by one side from the front of your car while you are busy trying to back up. That's a hypothetical scenario that could happen and it would be hard for someone to make an excuse because these lights should help the driver not be easily liable for an accident.
